* wl1251: move to it's own directoryKalle Valo2010-10-111-433/+0
| | | | | | | | | | | | | | wl1271 driver is under heavy development but on the other hand the older wl1251 driver is currently considered more as a legacy driver. To make it easier to develop wl1271 features move wl1251 to it's own directory, drivers/net/wireless/wl1251. There are no functional changes, only moving of files. One regression is that Kconfig won't be updated automatically and user needs to enable wl1251 manually with an older config file. Signed-off-by: Kalle Valo <kvalo@adurom.com> Signed-off-by: John W.

* wl1251: Fix queue stopping/waking for TX pathDenis 'GNUtoo' Carikli2010-08-311-1/+4
| | | | | | | | | | | | | | This patch was adapted from 06f7bc7db79fabe6b2ec16eff0f59e4acc21eb72 (from linus's linux-2.6 tree of kernel.org) here's the original message: The queue stopping/waking functionality was broken in a way that could cause huge latencies in TX transfers and even cause the TX to stall in the right circumstances. Correct these problems. Signed-off-by: Denis 'GNUtoo' Carikli <GNUtoo@no-log.org> Acked-by: Kalle Valo <kvalo@adurom.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* wl1251: fix ELP_CTRL register accesses when using SDIOGrazvydas Ignotas2010-03-151-0/+2
| | | | | | | | | | | | | | | | | | For some unknown reason ELP_CTRL can't be accesed using sdio_memcpy_* functions (any attemts to do so result in timeouts): wl1251: ERROR sdio write failed (-110) wl1251: ERROR sdio read failed (-110) wl1251: WARNING WLAN not ready To fix this, add special IO functions for ELP_CTRL access that are using sdio_readb/sdio_writeb. Similar handling is done in TI reference driver from Android code drop.

* mac80211: wait for beacon before enabling powersaveJohannes Berg2010-01-261-3/+0
| | | | | | | | | | | | | | | | Because DTIM information is required for powersave but is only conveyed in beacons, wait for a beacon before enabling powersave, and change the way the information is conveyed to the driver accordingly. mwl8k doesn't currently seem to implement PS but requires the DTIM period in a different way; after talking to Lennert we agreed to just have mwl8k do the parsing itself in the finalize_join work.

* wl1251: Implement delayed entry into ELP modeJuuso Oikarinen2009-11-181-0/+2
| | | | | | | | | | | | | | | Implement (slightly) delayed entry into ELP. This will cure several problems: - It works around a firmware race condition if ELP is entered too fast after commands (resulting in ELP timeout -traces) - It will reduce the number of sleep-wake cycles between already scheduled events such as interrupts and tx, hence improving performance (less delay in switching between RX and TX) Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Vidhya Govindan <vidhya.govindan@nokia.com> Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.

* wl1251: make irq handling interface specificBob Copeland2009-08-141-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In SDIO, the host driver requests the IRQ and invokes a callback to the card driver. This differs from SPI, so the relevant code needs to be interface-specific. This patch pushes the irq code down into _spi.c and _sdio.c, and adds enable/disable callbacks. This fixes the following warning: [ 566.343887] ------------[ cut here ]------------ [ 566.349105] WARNING: at kernel/irq/manage.c:222 __enable_irq+0x3c/0x6c() [ 566.356735] Unbalanced enable for IRQ 0 [ 566.361099] Modules linked in: msm_wifi wl12xx_sdio wl12xx mac80211 cfg80211 rfkill_backport lib80211_crypt_ccmp lib80211_crypt_wep lib80211_crypt_tkip lib80211 [ 566.381240] [<c025acec>] (dump_stack+0x0/0x14) from [<c004b610>] (warn_slowpath+0x70/0x8c) [ 566.391860] [<c004b5a0>] (warn_slowpath+0x0/0x8c) from [<c0077c10>] (__enable_irq+0x3c/0x6c) [ 566.402572] r3:00000000 r2:c02cad13 [ 566.407516] r7:00001002 r6:00000000 r5:c0310be4 r4:c0310be4 [ 566.415786] [<c0077bd4>] (__enable_irq+0x0/0x6c) from [<c0077fd0>] (enable_irq+0x38/0x64) [ 566.425826] r5:c0310be4 r4:a0000013 [ 566.430709] [<c0077f98>] (enable_irq+0x0/0x64) from [<bf0dfa78>] (wl12xx_boot_run_firmware+0xfc/0x170 [wl12xx]) [ 566.442947] r7:00001002 r6:c440a9fc r5:00000072 r4:c440a9e0 [ 566.450851] [<bf0df97c>] (wl12xx_boot_run_firmware+0x0/0x170 [wl12xx]) from [<bf0e05f0>] (wl1251_boot+0xd4/0x108 [wl12xx]) [ 566.464492] r5:00000000 r4:c440a9e0 [ 566.469466] [<bf0e051c>] (wl1251_boot+0x0/0x108 [wl12xx]) from [<bf0dd27c>] (wl12xx_op_start+0x54/0xb8 [wl12xx]) [ 566.482162] r5:00000000 r4:c440a9e0 [ 566.487472] [<bf0dd228>] (wl12xx_op_start+0x0/0xb8 [wl12xx]) from [<bf0b96dc>] (ieee80211_open+0x2dc/0x720 [mac80211]) [ 566.500594] r7:00001002 r6:c4950800 r5:c440a220 r4:00000000 [ 566.508865] [<bf0b9400>] (ieee80211_open+0x0/0x720 [mac80211]) from [<c01f1edc>] (dev_open+0x9c/0xfc) [ 566.520705] [<c01f1e40>] (dev_open+0x0/0xfc) from [<c01f17dc>] (dev_change_flags+0x98/0x170) [ 566.531417] r5:00000041 r4:c4950800 [ 566.536330] [<c01f1744>] (dev_change_flags+0x0/0x170) from [<c023041c>] (devinet_ioctl+0x3a8/0x784) [ 566.547683] r7:c128e380 r6:00000001 r5:00008914 r4:00000000 [ 566.555587] [<c0230074>] (devinet_ioctl+0x0/0x784) from [<c02318cc>] (inet_ioctl+0xdc/0x114) [ 566.566299] [<c02317f0>] (inet_ioctl+0x0/0x114) from [<c01e1a60>] (sock_ioctl+0x1f0/0x248) [ 566.576827] r5:00008914 r4:c572c1a0 [ 566.581771] [<c01e1870>] (sock_ioctl+0x0/0x248) from [<c00b23a0>] (vfs_ioctl+0x34/0x94) [ 566.592086] r7:c572c1a0 r6:bee497e8 r5:00008914 r4:c572c1a0 [ 566.599990] [<c00b236c>] (vfs_ioctl+0x0/0x94) from [<c00b2a28>] (do_vfs_ioctl+0x52c/0x584) [ 566.610549] r7:c572c1a0 r6:00008914 r5:c572c1a0 r4:c3201228 [ 566.618453] [<c00b24fc>] (do_vfs_ioctl+0x0/0x584) from [<c00b2ac0>] (sys_ioctl+0x40/0x64) [ 566.628890] [<c00b2a80>] (sys_ioctl+0x0/0x64) from [<c0021da0>] (ret_fast_syscall+0x0/0x2c) [ 566.639541] r7:00000036 r6:00000000 r5:00000004 r4:001a11f3 [ 566.647445] ---[ end trace 15c26ef7dd5e7b03 ]--- Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded devices, supporting both SDIO and SPI busses. Currently the driver supports only SPI. Adding support 1253 (the 5 GHz version) should be relatively easy.
